and visible ground. In addition, it can be used to add a 200A tap, or for the installation of an elbow arrester. The LRTP has a factory installed alignment guide with a shear pin that allows the alignment guide to disengage after installation. When the LRTP is screwed into the threaded insert of a bushing extender or threaded 600/900A compression connector, the alignment guide disengages once the proper amount of torque is applied.

B o t h t h e E T P a n d L R T P m e e t a l l t h e requirements of IEEE Standard 386, and are 200A three phase switching and three phase fault close rated.

The Chardon ETP and LRTP incorporate an all copper current path. This provides reliable and consistent performance under all conditions.

The Chardon Elbow Tap Plug (ETP) and Load Reducing Tap Plug (LRTP) are used to convert a standard 600A deadbreak inter face to a standard 200A loadbreak interface.

The ETP is ideal for applications where a 200A tap is desired for test or ground purposes. The ETP is also ideal for adding a 200A tap to an existing 600A T-Body connector. The 200A interface allows for live test, visible ground, addition of a 200A tap, or installation of an elbow arrester.

The LRTP is ideal for applications where the termination will be separated to achieve a visible break and ground. Having the T-body and LRTP connected, as one unit, makes it easier to install and remove from the mating bushing interface. The 200A interface allows for live test, phasing,
